Figure 2-1. Installation of Leg Assemblies
2. Attach two leg assemblies to each foundation foot and bolt the two leg ends to
the foundation foot using 3/4-10 x 4 1/2-inch bolt, washer, and nut in six places.
At one foundation foot, install a ground attachment lug to the leg ends before
bolting the leg ends to the foundation foot. Then ground antenna according to
local grounding codes.
3. As shown in Figure 2-2, position the leg support bracket, flanges down, on top of
the previously assembled leg junctures. Bolt leg support bracket in place at the
two inboard holes of each leg juncture using 3/4-10 x 2 1/4-inch bolt, washer,
and nut in six places.
4. Attach short extension of each support arm to the center hole at the underside of
each leg juncture using 3/4-inch bolt, washer, and nut in three places. Refer to
Figure 2-3.
5. Before fastening the support arms together, install a ground attachment lug to
the support arm at one of the center locations. Then attach a terminal lug to the
ground attachment lug using 1/4-20 x 3/4-inch screw, washer, and nut. This
will be used later to ground the antenna feed/LNBs.
